在深邃的海底世界，章鱼是当之无愧的“伪装大师”。当它游过珊瑚礁时，皮肤几乎在瞬间就能从米色变得灰褐，质感也从光滑变得粗糙，与周围岩石的纹理和色彩“完美融合”。人工材料能否像章鱼一样，拥有魔术般的“变装”能力？近日，《自然》杂志发表了美国斯坦福大学研究团队的一项新成果，受章鱼、乌贼等头足类动物启发，团队开发出一种新型聚合物材料，首次实现在单一器件上对表面视觉纹理和结构色彩的独立、动态调控。这项技术有望为动态伪装、自适应显示、智能建筑以及互动艺术等领域，提供全新的解决方案。

If you’re a casual college basketball fan, an option like Sling may be a good fit for you. It's a comprehensive sporting service with a wide range of benefits, but you will need to be careful when selecting your plan. The Orange and Blue packages give you access to FOX, NBC, ABC, ESPN, and more in local markets — for $45.99 per month (with an introductory deal of 50% off for the first month) — but for access to ACC Network, SEC Network, Big Ten Network, and more, you'll need the Sports Extra package. We recommend checking your local market to ensure you get access to the channels you actually want.
